Priority Core Area (PCA) and Priority Linkage Area (PLA) geodatabase

This Esri file geodatabase contains the Arid Lands Initiative's Priority Core Areas (PCAs) and Priority Linkage Areas (PLAs). For all PCAs and PLAs over 5,000 acres in size, we developed a "scorecard" that presents its rank, relative to the other PLAs, for a range of threats and values.  Both the raw, continuous values and the ranks are available in the attributes of these feature classes. Details about each field are provided in the fields metadata section. The citations in the fields metadata can all be found in the references section of the Phase 2 final report, available here. 

The full report with PCA scorecards is available here, and the addendum report with PLA scorecards is here.

Most of the raw input rasters and other layers used to derive the metrics for PLAs and PCAs are provided in an input layers geodatabase, here.
